I think single cell design may be a good solution for retrofits on older, smaller ships where space is at a premium, like Indonesia is planning. When the other option is nothing, 2 on one side, 4 on the other doesn't sound too bad without increasing costs enormously for an older ship.
If you are referring to Malaysian LMSB2 project it has VLS cells compatible or larger cell width to Mk41/MIDLAS and holds 4 missiles, linked to a single exhaust line, whereas Göksur VLS is rather in dimension of JAGM QUAD per cell and each cell has an individual exhaust.
So given the size of Göksur VLS cell and the single missile it holds, the individual cell is lesslikely to be used alone, it will be at least a stack of 2 - 4 to 1 or 2 to 2.
To win against Roketsan's single and short MIDLAS Aselsan has to come up with a better solution to cover more than just boat classes. Launching Kuzgun, Bozdoğan - Gökdoğan and UAVs with cold launch mechanism sounds like a good way to me and the partner - TÜBİTAK SAGE has studied cold launch earlier.
